Which characteristic describes crosstalk?

Question:
Which characteristic describes crosstalk?

• the distortion of the network signal from fluorescent lighting
• the distortion of the transmitted messages from signals carried in adjacent wires
• the weakening of the network signal over long cable lengths
• the loss of wireless signal over excessive distance from the access point

Explanation: EMI and RFI can distort network signals because of interference from fluorescent lights or electric motors. Attenuation results in deterioration of the network signal as it travels along copper cabling. Wireless devices can experience loss of signals because of excessive distances from a access point, but this is not crosstalk. Crosstalk is the disturbance caused by the electric or magnetic fields of the signal carried on an adjacent wire within the same cable.
